someone told me to use a router. Can you explain what it is, how it works and how I use it, please?
TIA.  |

Yeah, that link explains it pretty well, but don't be put off by the size of the router on the first page. My home router, for instance, is smaller than a desk phone. I've used it to connect my Mac to my PC and I can move files back and forth that way.
Can I ask why you're thinking about a router? It could be that a hub or a crossover cable might be sufficient. Routers are usually about $100, hubs more like $40 and crossover cables are $10-- although don't quote me on those prices. |

Thanks. I am told a router is 45,000 from Yongsan.
By the way, I read that page and some other stuff but it's too technical for my baby_teething_sleep_deprived_brain... So can I have someone explain it to me in very, very simple English, please?

| A router lets computers connected to it share an internet connection (for example, three computers are connected to the router and the router is connected to the modem). It also lets computers connected to the router share data between each other. My guess is that you have two or more computers that you want to connect to one modem, or that you want to share data between two computers. If you're just sharing data, you can simply get a crossover cable. If you want to share an internet connection, the router is the simplest way to do it. |

| I saw a wireless router that will connect up to 5 (I think) computer for only 60,000 in the ���� building. |

Do you remember where, and whether it was 802.11b or g?
I'm tempted to get one so I can use my laptop in bed. Ahem. |

| tzechuk - please bear in mind that if you go with the wireless router, you will have to buy adapters that you will install into the computer to enable your computer to access the wireless router. I suggest you not get the wireless router because it is a needless expense (You have to buy the wireless router along with a wireless adapter for each of the machines that will connect to it - unless they have wireless capability already installed - compared to just the wired router along with the wiring for what you already have - I assume that you already have network adapters installed on all your computers and, therefore, don't need to buy adapters to connect to the wired router). Furthermore, wireless networking tends to make all computers connected to it vulnerable to all kinds of nasty things unless you can configure it properly. Lastly, because I think wired data transfer rates tend to be faster anyway. |

The data rate between wirelessly connected computers is still going to be an order of magnitude greater than the data rate from the computers to t'internet. The only exception to this is if your neighbours are already saturating the building with wireless signals (there are only three non-overlapping channels available on 802.11x).
The likelihood of being catching something nasty from the internet is far greater than from a wireless network. A bigger problem would be someone soaking up your bandwidth, if you didn't configure properly. It's worth checking which security protocols your router and computers share before making a decision.
The cost bit I'd agree with - but if you have a laptop there's really no going back to wired, so you would have to weigh up cost and convenience. Even if you don't, it may cut the clutter sufficiently for you to decide it's worth it. |

Okay, I admit I really don't know much about computers. I just follow my common sense when it comes to setting up and troubleshooting. The internet is also a good resource for learning about this tech mumbo jumbo, but there's always going to be someone out there that knows more than me, so I'm open to an education.
Here are some reasons behind my statements. Please feel free to correct me if I have been misinformed.

Operative word was "I think." 100 Mbps wired vs. 54 Mbps wireless. Are there faster wireless connections now? I must be behind times. Or am I confused about the connection speeds here? Granted, you might not even get service with 100 Mbps, or even 54 Mbps, but I like having overhead. It gives you leeway to communicate between computers on the local network at the same time as downloading like crazy off the internet.

I agree that there are big(ger) nasties out there on the internet. However, if little Kim Jr. out in Busan is checking my computer over here in Geumchon for open ports every so often while I'm connected to the internet, I'd be pretty paranoid about other kids like him tooling around town with a wireless network detector and a laptop. I think some other guys in this forum were saying stuff about the neighbours that they have in their buildings and the ports that they're leaving open on their wireless networks giving them something to have fun with late at night. It's pretty easy to scan an area for open wireless networks. Granted I'm a little paranoid, but it's just another open door that I think should stay shut. Of course you can fix this by locking the network down, but it's just that much more hassle for me over the wired network. At least with the wired network, I don't have to wear my metal beanie because of crazies that want to broadcast signals into and out of my brain and my computer. And nobody's going to soak up my bandwidth, either, unless they snuck in and connected to my router without my knowledge. Maybe I should be keeping a rifle sight on that darned little contraption.

Money money money makes the world go 'round, the world go 'round, the world go 'round.
Usually, when I use my laptop at home, I've already got it connected to an AC adapter plugged into the wall anyway. So it's not really much of a hassle if I stick a network cable in, too, because it's not going to move much because of that connection to the power outlet.
However, if you have a laptop with wireless networking already built in, you might want to go ahead and go wireless. You don't have to pay for that extra wirelss adapter if you already have it anyway and I think you can go that extra man or two for the wireless router. It would just mean one less wire for me to stick into the laptop. But you've still got to tether the thing sometime anyway, because the battery has got to be recharged. Hm. wireless battery recharger/power supply. Is there a patent on that, or has it already been invented? Why am I still chained to my desk, anyway?
Sorry if there was any confusion in my previous post. |

Right, thanks, understood.
So how does a router protect me from being attacked by virus?! |

I don't know, I was only checking prices as this is a future purchase. Just wanted to get an idea of the going rate. |

The address the outside world sees is held by the router, not by your computer. The router translates addresses between the outside world and your internal network. So nasty programs like viruses find it harder to make a direct connection to your computer to do bad things.
It only protects against certain kinds of viruses and other malware, but it's a good additional line of defence nonetheless. No substitute for the proper firewall and virus protection software on your computer though. |

Thats part of the answer, the other half is that routers nowadays also act as a firewall that block certain ports that are vulnarable. You need to configure the router to allow the ports you want.
Actually, usually a hardware firewall is better than a software one. |

What is a hardware firewall and a software firewall and can you recommend one for me to buy
Thanks. |
